throw er; // Unhandled 'error' event&Error: ENOENT: no such file or directory,

今天做一个文件上传的项目时, 用express-formidable往硬盘里面存文件时, 报  ENOENT:no such file or directory

原因就是程序不能像别的语言一样不存在就创建文件夹, 只有手动创建文件夹. 程序才能运行正常.

events.js:183
throw er; // Unhandled 'error' event
^
Error: ENOENT: no such file or directory, open 'D:learningmyblog_v3publicimgupload_ff831a558a928941ffac1784584a8db9.png'
